Core Viewpoint - Huawei Digital Energy has successfully completed the industry's first fire safety test for commercial energy storage solutions based on the latest UL9540A:2025 standard, setting a new safety benchmark in the industry [1][7]. Group 1: Extreme Testing Environment - The test created an unprecedented harsh environment to comprehensively validate the safety performance of the energy storage system under extreme conditions [3]. - The testing method involved triggering thermal runaway in 60 battery cells simultaneously, significantly increasing the test's severity compared to traditional methods [3]. - The test conditions included using an open-door combustion scheme defined in UL9540A:2025, fully charging all battery packs to 100% state of charge (SOC), and disabling all fire protection systems to assess the system's inherent design under maximum stress [3]. Group 2: Robust Safety Design - Huawei's commercial energy storage solution features an innovative five-level protection design that demonstrated exceptional safety performance under extreme testing conditions [4]. - Key safety features include: - Thermal insulation design between battery cells to slow down the spread of thermal runaway [4]. - A full metal shell capable of withstanding temperatures over 1500°C, maintaining structural integrity during a fire [4]. - A unique positive pressure oxygen-blocking and directional smoke exhaust design to effectively divert combustible materials [4]. - A labyrinth structure at all sealed interfaces to prevent flame spread [4]. - Comprehensive fire-resistant protection for the storage cabinet [4]. Group 3: Performance Data - Key data collected during the test confirmed the safety and reliability of Huawei's commercial energy storage solution [5]. - At a fire temperature of 961°C, the maximum temperature of adjacent battery cells was only 45.3°C, well below the threshold for venting, meeting UL9540A:2025 standards [5]. - The maximum heat release rate recorded was 3MW, with total burn duration of less than 3 hours before self-extinguishing, showcasing excellent thermal management capabilities [5]. Group 4: Industry Leadership - The extreme combustion test, witnessed by TÜV Rheinland, not only validated the safety performance of Huawei's energy storage solution but also provided valuable safety verification experience and templates for the industry [7]. - Huawei Digital Energy's joint declaration of a "full lifecycle safety quantitative assessment system for electrochemical energy storage systems" has been recognized as internationally leading by industry experts [9]. - The success of this extreme combustion test demonstrates a new height of safety for commercial energy storage, marking a milestone for the industry's large-scale safe application and healthy development [10].
